棉织物的β-环糊精接枝研究

Citric acid as crosslinking agent for grafting β-cyclodextrin onto cotton fabrics

采用柠檬酸 (CA)作为交联剂 ,将 β 环糊精 (β CD)接枝到棉织物上 ,研究CA和 β CD浓度、焙烘条件(温度 ,时间 )以及催化剂的种类和浓度等对 β CD接枝率的影响。研究结果表明 ,β CD的加入对织物增重率的提高作用很大。该课题通过对织物的增重率和吸香释香能力等进行了测定 ,对接枝到织物上的 β CD作了验证。

In the paper,citric acid(CA) as crosslinkin g agent for grafting β-cyclodextrin(β-CD)ont o cotton is studied. The factors affecting the ratio of grafting of β -CD such as the concentration of CA,the catalyst and β-CD,cure condition (temperature,time),the nature of the catalysts were stud ied. As a consequence,the use of β-CD can increase weight gai n of fabrics markedly. The grafting of β-cyclodextrin onto cot ton fabrics was identified by different ways such as weight gain of fabrics and the ability of inclusion and release of fragrance.
